[0002] A cam bearing is a type of bearing, generally used for automotive camshafts (the shaft that controls the opening and closing of the valves in a piston engine). The bearing seat is the base component for assembling the shaft body. When machining it, a jig is required for clamping and fixing. For example, the publication number is CN216264627U, named "bearing seat jig", which includes: a base, a rotating shaft assembly, a limiting assembly, and a clamping member. One end of the clamping member is connected to the base through the rotating shaft assembly, and the other end is connected to the limiting assembly. The bearing seat to be machined is clamped between the clamping member and the base. The clamping member is a rigid frame structure with several connecting holes, and the clamping member is correspondingly connected to the rotating shaft assembly through the several connecting holes. The clamping member buckles towards the side close to the bearing seat with the connection point of the connecting holes and the rotating shaft assembly as the axis, so that the bearing seat to be machined is clamped between the frame-shaped clamping member and the base. The base is provided with a positioning through hole, which penetrates from the top surface of the base to the bottom surface of the base.
